Imagine painting with a broad brush an entire nation’s worth of people, one with literally several or many times more people than name a European country.

We’re a country of many peoples with many values and that’s one of the reasons we fight so much. Pretty much everything you listed is a norm which evolved from a strict—and yes, sometimes puritanical view—to accommodations for different people from the heart of the Tennessee River Valley to the beaches of California.

We’re not all still partying like we’re fresh off the boat and it’s 1620. As clean as a Hollywood production might look to you, the people that made that movie were probably all living rather diverse lifestyles, many of whom might make a Roman at their peak blush. The Puritanism is still there, but so is a lot more than that.
